Android 4.2.2 has been rolling out to a number of Nexus devices this week, and today it has popped up on the LG Nexus 4 for the first time. It brings all of the changes and improvements that the other devices are getting, and addresses a trick that allowed users to activate LTE on the device.

The 4.2.2 update fixes a number of key issues in Jelly Bean, including a Bluetooth streaming bug that has been a big problem for Nexus users. It also makes a number of small changes to certain parts of the operating system — including the Quick Settings menu and download notifications — which we covered on Wednesday.

For Nexus 4 users, who are getting the update for the first time today, the update has another function; it kills the trick that allowed the unofficial activation of LTE.

The Nexus 4 doesn’t support LTE networks, but shortly after its release, developers found that it did have the technology to support certain LTE bands. With a bit of trickery, LTE could be activated, but it was only available in certain areas on certain carriers — so it wasn’t of much use to most users anyway.

It was kind of inevitable that Google would kill the trick sooner or later, so it’s hardly a surprise that this has happened in the latest Android release.

The update comes with the “JDQ39″ build number, and weighs in at about 54MB. You’ll receive a notification when it’s available for download, but you can also check for it manually by visiting the system updates section within the Settings app.
